Description Balló György 2024-03-07 13:04:08 UTC

SUMMARY
After I login into the Plasma (X11) session and open Dolphin or Konsole from the main menu, the panel become unresponsible for left clicks. E.g. if I left click on the main menu, nothing happens. I have to hit Alt-Tab, or Meta, or just right click on the panel to make the panel responsible again for left clicks. It happens only with the Plasma (X11) session, the Wayland session works fine.

STEPS TO REPRODUCE
1. Login into the Plasma (X11) session.
2. Open Dolphin or Konsole from the main menu.
3. Left click on any button on the panel.

OBSERVED RESULT
The panel does not respond, nothing happens.

EXPECTED RESULT
Clicking an a button should do the proper action, e.g. open the main menu, switch applications etc.

No, it's Mesa Intel(R) Graphics (ADL GT2) with modesetting Xorg driver.

Is this with forcing QtQuick to software mode using QT_QUICK_BACKEND=software? If so, does it start working if you stop doing that?

No. It happens without setting the QT_QUICK_BACKEND envvar.

I can't reproduce this problem anymore, so I'm closing this task.
